Drill bit AWTools AW42893 — model AW42893, weight 1.51 kg

AWTools AW42893 drill bit is a replacement drilling accessory designed for masonry and stone applications. Constructed from 40CR alloy steel with a YG8C tungsten carbide head, this AW42893 model combines a durable shank and a hard cutting tip to perform drilling in concrete, granite, natural stone, brick and ceramic tiles. The bit weighs 1.51 kg and features an SDS+ grooved shank for secure retention in compatible hammer drills and rotary impact hammer drills.

Advantages

The 2-cutter spiral design promotes efficient removal of spoil, reduces vibration and helps prevent overheating of the cutting edge. The YG8C carbide head provides wear resistance and maintains cutting performance when working with abrasive materials. The 40CR alloy steel body offers toughness and resistance to bending under load, while the grooved SDS+ shank ensures stable engagement with the tool to prevent the bit from falling out during use.

Suitable for

• Drilling anchor and fixing holes in concrete and masonry
• Creating openings in granite and natural stone for installations
• Drilling through brick and ceramic tiles during renovation work
• Use with hammer drills and rotary impact hammer drills requiring an SDS+ shank

How to use

Install the AWTools AW42893 drill bit into an SDS+ compatible hammer drill or rotary impact hammer drill by aligning the grooved shank with the tool chuck and engaging until it locks. Select an appropriate rotational speed and hammer mode for the material being drilled; lower speeds with hammer action are typically effective for hard materials like granite and concrete. Apply steady pressure, allowing the bit to cut and the spiral flutes to evacuate dust and debris. Withdraw periodically to clear spoil for deeper holes and to avoid excessive heat buildup. After use, clean the flutes and inspect the carbide tip for wear before storage.

Usage recommendations

Use personal protective equipment, including eye and hearing protection and a dust mask when drilling masonry or concrete. Match drill speed and hammer settings to the material, and avoid excessive side loads to prolong the life of the carbide head and the steel body.
